Problem

Consider the curve given by xy+y2=10xy+y^{2}=10. Determine the slope of the tangent line at the point (2,3)(2,3). a) 38\dfrac{3}{8} b) −83-\dfrac{8}{3} c) −38-\dfrac{3}{8} d) −12-\dfrac{1}{2}
Intuitive explanation

This is an implicit differentiation problem—you're finding a slope when yy isn't solved for explicitly. The key insight is to differentiate both sides with respect to xx, treating yy as a function of xx and applying the chain rule and product rule as needed. Once you have an expression for dydx\frac{dy}{dx}, substitute the point (2,3)(2,3) to get the slope at that specific location.
